Giga Pudding is a viral internet phenomenon originating from a Japanese television commercial for a massive DIY custard pudding kit by Takara Tomy. The meme gained global notoriety on sites like 4chan and YouTube around 2010 due to its incredibly catchy and repetitive 'Puddi Puddi' jingle. It typically represents chaotic joy, obsession with sweets, or general internet absurdity. Users often use the template to express overwhelming excitement or to parody the infectious nature of the original advertisement's earworm song, making it a staple of early 2010s internet culture.
